wx.chooseMedia({
count: 1,
mediaType: ['video'],
sizeType: ['compressed'],
sourceType: [sourceType],
maxDuration: 60,
camera: 'back',
)}
# 问题：
- 最近将wx.chooseVideo替换为了wx.chooseMedia，并使用wx.canIUse('chooseMedia')做了向后兼容，结果埋点发现有大量异常
- 用户调用chooseMedia上传视频，直接走了fail回调，异常信息：{errMsg: "chooseMedia:fail"}
- 每天有大量异常，无法复现，埋点排查设备、微信版本都没什么规律
# 此类问题相关的帖子：
# 后续
- 咨询了微信侧研发，发现是用户进入相册或者拍摄页面之后，直接把微信退到后台，导致取消的，就会报这个错
- 因此这个报错不能作为实际问题发生的依据
完整报错是什么 请具体描述问题出现的流程，并提供能复现问题的简单代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）。
我这边也有遇到，真机复现了 华为 Pura 70，和切到后台没关系，是内存占用太高，把后台都杀掉就正常了
一样的问题，把错误发到服务器抓，少量用户，相册选择图片直接报这个错，大部分都是正常的，各种查没查到问题

我是发现通过微信聊天拍摄，保存下来的视频，无法上传，直接返回{"errMsg":"chooseMedia:fail"}，如果把这个视频单独保存一下，就能上传了，人麻了
{"tempFiles": [], "errMsg": "chooseMedia:fail", "type": "mix", "failedCount": 1}这个方法在PC端有很多问题，之前咨询过说是设置了maxDuration的原因，PC端不支持那么长的
